Impulse and unsanctified passion exist in the place of pure love. Many imperil their own souls, and bring the curse of God upon them, by entering into the marriage relation merely to please the fancy. I have been shown the cases of some who profess to believe the truth, who have made a great mistake by marrying unbelievers. The hope was cherished by them that the unbelieving party would embrace the truth; but after his object is gained, he is further from the truth than before. And then begin the subtle workings, the continued efforts, of the enemy to draw away the believing one from the faith. (4T 504.1) MC VC

Many are now losing their interest and confidence in the truth because they have taken unbelief into close connection with themselves. They breathe the atmosphere of doubt, of questioning, of infidelity. They see and hear unbelief, and finally they cherish it. Some may have the courage to resist these influences, but in many cases their faith is imperceptibly undermined and finally destroyed. Satan has then succeeded in his plans. He has worked through his agents so silently that the barriers of faith and truth have been swept away before the believing ones have had any thought of where they were drifting. (4T 504.2) MC VC

It is a dangerous thing to form a worldly alliance. Satan well knows that the hour that witnesses the marriage of many young men and women closes the history of their religious experience and usefulness. They are lost to Christ. They may for a time make an effort to live a Christian life, but all their strivings are made against a steady influence in the opposite direction. Once it was a privilege and joy to them to speak of their faith and hope; but they become unwilling to mention the subject, knowing that the one with whom they have linked their destiny takes no interest in it. As the result, faith in the precious truth dies out of the heart, and Satan insidiously weaves about them a web of skepticism. (4T 504.3) MC VC
